What is the sequence for 6,12,18,24

scoundrel [369]

Answer:

an =6n

Step-by-step explanation:

6, 12, 18, 24

Take the 2nd number minus the first number, 3rd minus the second, etc

12-6 =6

18-12 = 6

24-18 =6

The common difference is 6

The formula for an arithmetic sequence is

an =a1+d(n-1)

where a1 is the first term

d is the common difference

n is the term number

an = 6+6(n-1)

Distributing

= 6+6n-6

= 6n

Find the percent of increase or decrease? 2.5y to 1.5y

horsena [70]

Answer:

From 2.5 y to 1.5 y there is a 40 % DECREASE in the value.

Step-by-step explanation:

Here, the initial value = 2.5 y

The final value of 1.5 y

Now,as Final Value < Initial Value

So, there is a DECREASE IN THE VALUE.

Now, decrease in the value = Initial value - Final Value

= 2.5 y = 1.5 y = 1 y

or, there is a decrease of ( 1 y) in the given value.

Now, Percentage decrease in the value is given as:

$\textrm{Percentage Decrease} = \frac{\textrm{The decrease in the value}}{\textrm{The initial Value}} \times 100\\ = \frac{1 y}{2.5 y} \times 100 = 40$

or, Percentage Decrease = 40%

Hence, from 2.5y to 1.5y there is a 40 % DECREASE in the value.
